Succulents In Recycled Containers

I love to collect tiny containers (bought from thrift shops) for my succulent collections; if I see an interesting shape (plastic animal mugs, etc.) I drill drainage holes in them and fill them with succulents.

Awesome tip. Can you please tell me what type of drill tip you use for putting holes in the ceramic stuff? I tried once a long time ago and it just shattered the container. You must have a special trick! Please tell!
